SPECIFICATION forming part of Letters Patent No; 399,944, dated'march 19, 1889.

' Application mea my 21, 188s. seran No. 230.632. un model.)

To all whom it may concern.:

Be it known that I, FURMAN D. SPEAR, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Lantern-Frames, of which the following is a full, clear, and exact de scription, reference being had to the-accompanying drawings, and to the letters of reference marked thereon.

My invention relates to lantern-frames, especially such as are employed upon handlanterns, but is likewise applicable in the constructiony of frames for lamps and similar illuminating devices.

- The object of my invention is to provide or produce a frame of the class named which shall be self-,sustaining before soldering or tinning, which shall be rigid and durable, and at the same time as light as is consistent with its required strength, which may be madewith much economy of labor and material, and ofwhich the parts may be compactly shipped, ready to be afterward assembled.

To accomplish all of this and to secure other and further advantages in the matters of construction and' assembling, my improvements involve certain new and useful arrangements or combinations of parts ,andl peculiarities of construction, as will be herein first fully described, and then pointed out in the claims.

In the accompanying drawings, forming part of -this specification, Figures 1 and 2 are views in elevation showing lantern-frames, each completed 'in accordance with my invention and ready to receive any suitable appendages, the first view, Fig. 1, omitting the base part or foot; which is represented in the second metal, showing the manner in which the ringguards may be cut therefrom with economy of material. v *Y In all the figures like letters of reference,

'wherever they occu'r, indicate corresponding parts.

The horizontal-ring guards vor bands of the frame are representedat a, l), c, (l, and e, and the upright guards at f g h h. The number of horizontal ring-guards and the number of upright guards may be varied according to circumstances; ut of the ring-guards three or more should e employed, so-that the parts may be braced and held in place to form a. self-sustaining frame without the aid of other appliances. In the example chosen for illustration herein, which is -a frame of ordinaryl exterior thereof, as at 1i t', Fig.,3, and the notches inthe next ring-guard being on or in the interior thereof, 'as at k k, Fig. 4. -The upright guards are notched on each side, as at l l', Figs. fand 6, at points Where the ringguards are to be located, the notches alternating from side to side. The upright guards and ring-guards are interlocked at the notched parts halved together, as suchv forms of joints are usually indicated. i

It is vapparent that the above arrangement of alternately locating the horizontal ringguards on the inside and outside of the upright guards makes the strongest possible assemblage; yet other orders may be employed with good results--as example, one or moreof the central' horizontal ring-guards being located on the inside or outside of the upright guards and the next one o1' more above and vbelow being located on the opposite side of the upright guards. So, also, may there be many variations in the orders of notching the ring-guards and the upright guards with good results. One or more notches may be omitted from one or more of the ring-gu:xrds, thereby depending upon the notches in the upright guards for holding them in place. Likewise one or more notches in one or more of the upright guards may be omitted, depending upon the notches in the ring-guards for support, but for uniformity of part, simplicity 0f assembling, and to procure the greatest possible strength in my construction, I prefer to em- IOO terlocked at the proper points. Then the next ring-guard is located and interlocked, and so on until all are in place, the notches and ringguards forming all the guides and gages that are necessary, and the frame being self-sustaining from the start. When thus completed, it will be observed that the uncut portion of any upright guard is located iirst on the inside of one ring-guard and then on the outside of the next, being thus in a manner woven in and out of the series of ring-guards,

by which all -.the parts are most effectively braced and' held in proper' relation.A This interlocking of the parts together and weaving of the upright guards in and out may be accomplished whether the parts be made of flat metal or round, either form being intended to be used in this part of my invention. After the frame is assembled substantially as above indicated it is intended to be trimmed and all joints securely closed or soldered together at one single operation by dipping in molten tin, or by equivalent process. By making the parts of flat metal, each considerably broader than it is thick, and locating thering-guards horizontally and the upright guards in planes passing through the vertical axis of the frame,

it is plain that the metal is best opposed to.

any damaging strains. The ring-gu ards may be cut from a sheet of metal, as A, Fig. 7.

Lantern frames occupy considerable space in shipping. Vith my improved form of frame the part-s may be very closely packed,

to be assembled on reaching their destination.. Thus the saving in shippingspace, freight, dac., will be very considerable. Aside from this, no skilled `labor whatever is required in the manufacture of this frame, and

no handlabor other than that required to feed the blanks into the cutting-tools and afterward to place the parts in proper relative positions, the parts being ready for use as they leave the dies or cutters.- Two of thev upright guards,as h h, may have perforated ears, as

m m, to receive the bail or handle. y

So far as this frame is concerned, the lamp or lantern fittings may be applied in any way, 4and are not claimed herein.

When the parts are constructed and assembled substantially in accordance with the foregoing explanations, the improved frame has been found to admirably answer the purpose or object of the invention as previously set forth. l

Having now fully described my invention, what I claim as new herein, and desire tose cure by Letters Patent, is-

1. In a lantern-frame, a series 'of three' 4or more horizontal ring-guards, combined With'a series of upright guards, the vupright guards being locked inv place by the ring-guards to form a selffsustaining frame, substantially as set forth.

2. In a lantern-frame, a series 'of three ,or more notched horizontal `ring -'guards, combined with a series of upright guards, and the parts bein ginterlocked and arranged or woven together, substantially" as and for the purposes set forth. f

3. In a lantern-frame, a series of three or more horizontal ring-guards, combined witha series of notched upright guards, and theparts being interlocked and arranged or woven together, substantially as and for the purposes set forth. v

-1. In a lantern-frame, a'sries ofv three or more horizontal ring-guards, combined with a series of upright guards, both being notched and the parts being interlockednd arranged or woven together, substantially as and for the purposes set forth.

5. .In a lantern-frame, a series of three or .more horizontal ring-guards, of which series the rings are alternately notched on the interior and exterior, combined with a-'-1'ies o f upright guards notched on opposite faces, the

parts being interlocked and arranged or woven' together, substantially'as and for the purposes set forth.

6. In a lantern-fram,.tl,e coibination of three or' more hat metal ring-guards and flat metal upright guai-dattie' ring-guards, being notched or hal'yed inm. orflupon the upright guards, which are also notched, the parts being interlocked-and interwoven, substantiallyas and for 'the purposes set forth.I

7. In a lantern-frame, the combination of three or more continuous 'flat 'metal ring- IXO guards and fiat *metal .upright guards, thef ring-guards being vnotched .or halved into or upon'the upright guards, the parts being interlocked and interwoven, substantially as and for the purposes set forth.

8. In alan tern-frame, the combinatiomwith three or more horizontal flatl metal rings bands, of hat metal uprights connected with said rings and' arranged in planes passing through the axis of the frame, substantially -as and for the purposes setforth.

In testimony that I claim lthe foregoing I have hereunto set my hand in the presence of v two Witnesses.
